“There is one point that we may have underestimated: the time that we devoted to the merger,” Publicis Chief Executive Maurice Levy said earlier Tuesday. “That has certainly weighed on our performances.”

Omnicom executives, in contrast, didn’t mention any distractions from the deal and said it’s on track to meet its full-year targets.

“Most of our businesses did fairly well, so we didn’t have a lot of headwinds in any one spot. That is always a plus,” said Omnicom Chief Financial Officer Randy Weisenburger in a conference call with analysts.

The $35 billion merger-of-equals, which would have created the world’s largest ad holding company, fell apart for reasons including disputes over top roles in the combined company and regulatory approvals. Omnicom and Publicis, which had sought to merge to better compete with digital giants like Google and Facebook, will now have to navigate an evolving industry on their own.

Omnicom’s organic growth – a key metric in the ad industry that strips out currency shifts, acquisitions and disposals—was 5.8% for the quarter, a rate that analysts said could be the best in the industry for the quarter. The company’s results were particularly strong in the U.S., driven by its media operations. Omnicom said it has won new business from well-known brands such as Johnson & Johnson, CVS, Sony and Heinz since the start of the year.

“We won a lot of business this past quarter,” Omnicom Chief Executive John Wren said on a conference call with analysts Tuesday. “I don’t believe Publicis is where we have gotten it from. I think our wins really have come from Interpublic and WPP.”

Publicis, meanwhile, posted 0.5% organic sales growth, hurt by delayed or canceled spending by some clients and weaker-than-expected performance in emerging markets and Europe. The company has also been stung by some account losses and has seen some of its big accounts placed in review including Samsung Electronics.

Publicis, which has long touted industry-leading margins, said its operating margins for the first half of the year fell to 13% from 13.7%, partly because of a change in the way it accounts for some contracts to include the costs associated with buying media space.

Omnicom’s second-quarter margins also fell, to 14.2% from 14.4%, due in part to the impact of foreign exchange and $1.8 million in costs related to the merger.
